Online user electricity consumption information monitoring method

The invention provides an online user electricity consumption information monitoring method. The method comprises the following steps: acquiring real-time data information and fault data information of a line at the side of a special power supply line of a master station user; processing or screening the real-time data information and the fault data information; and storing the processed or screened real-time data information and fault data information in a real-time database management system. The running status of a power grid is predicted and monitored in real time by means of acquiring the real-time data information of the line, and the data which are missed or become abnormal before or after a fault occurs can be effectively remedied by means of acquiring the fault data information of the line, so that the data integrity is guaranteed; in addition, since the acquired data information is stored in the real-time database management system, the judgment and the processing of faults can be facilitated and consequently a solid guarantee is provided for the safe production of electricity as well as the safe and reliable running of important users such as high-speed rails.
